SAFETY CATCH FOR BROOCHES AND THE LIKE.

Application. filed May 1, 1923.

To all whom it may 6'01106771.

Be it known that KARL ZACK, a citizen of the United States, residing at Denver, in the county of Denver and State of C010- rado, has invented certain new and useful Improvements in Safety Catches for Brooches and the like; and he does hereby declare the following tobe a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in safety catches for brooches, bar-pins and the like, and has for its object to provide a catch which will not become accidently opened. Briefly stated the invention consists in the provision of a slidably and pivotally mounted latch in connection with its keeper, means being provided to hold the latch against sliding movement after the same has been closed- The various novel features of the invention will appear from the detailed description taken in connection with the accompanying drawing forming part of this specification. y

In the drawings, Fig. 1 is an end elevation of the improved safety catch showing the same in locked position.

Fig. 2 is a side elevation of the same.

.Fig. 3 is an end elevation showing the same in opened position.

Fig. 4 is a side elevation looking at the back of the keeper, the lock being open.

Fig. 5 is a plan of Fig. 4.

Fig. 6 is a vertical section on line 6-6 of Fig. 3.

Fig. 7 is an end elevation of the keeper and Fig. 8 is a view showing the application of the invention to a brooch or bar.

In the drawings numeral 1 indicates the body of the brooch or bar, with which the.

improved catch may be employed, and numeral 2 designates the pin proper which is pivoted at one end to the body 1 and at its other end is adapted to be received within the lock. The keeper is indicated at 3 and is provided with a. hook shaped end having a notch 4c in the top thereof which is adapted to form a seat for a projection 5 at the free end of the latch 6, which is pivoted on a pin 7 mounted in the keeper. The keeper is provided with a cut-out as indicated at 8 and is of sufficient length to allow the latch to be shifted along the Serial No. 635,988.

pin for a short distance. This distance is determined by the width of a lateral shoulder 9 on the latch 6 adjacent the bear- V ing opening in the latch.

This shoulder is adapted to be disposed in front of a shoulder 10 on the keeper 3,

said shoulders when in abutting relation serve to prevent relative turning movement between the keeper and the latch. When the latch is slid'or moved on the pin? away from the shoulder 10 it may be turned upon its )ivot 7, and swun open as shown in Fig. 3.

The opening 8 extends through the keeper 3 from one side to the other and mounted near the base of the keeper is a finger 11 which is adapted to be swungtoward the pin 7 in the path of slidable movement of the latch 6, when the latch is in closed position as in Fig.1. .lVhen the finger is disposed in the position stated the latch 6 may not he slid along the pin 7. The finger 11 is mounted in any suitable manner as on a pin 12, and when in closed position will lie flush with the back of the keeper.

finger is swung into functioning position it will be disposed along the side of the heel of the projection 13 as is clearly illustrated in Fig. 1.

The finger 11 is cut away on its inside and terminates in a pointlike member so that the finger can be readily gotten ahold of by the fingers of the hand when it is desired to unlock the improved catch. The latch 6 is provided with a rib 15 which will serve as a finger hold or abutment for the fingers of the hand when it is desired to shift the latch on its pin 7.

The operation will be readily understood. pin 2 into the catch the latch is opened as in Fig. 3. After the pin has been disposed beneath the hooked part of the hen it is desired to insert the I keeper the latch is swung on its pivot and the knob or projection 5 thereof sprung over the en'd of the latch until the knob is seated in the recess or pocket 4 in the top of the keeper. The latch is then shifted along the pin 7 to the limit of its movement in which position the shoulders 9 and 10 wouldbe in abutting relation as shown in Fig. 1 and the extension 13 of the latch will underlie the shoulder 14 of the keeper. Thei'enpon the finger 11 is swung into closed positionwith the result that the same forms a stop which will prevent shifting of the latch 6 on the pin/7.

ll hat isclain'ied is: V p l.' The combination with a keeper, of a latch pivotallv and slidaloly mounted there' on the latch being locked against turning when atone end of its slidalole limit and freely turnalole when displaced from said limiti and releasable stop member cooperating with the latch to hold the same against sliding movement. I I p 2. The combination with a keeper, of a latch pivotally and slidably mounted thereon, cooperating means on the keeper and latch adapted to ihterlock when the latch is at one limit of its sliding movement and a swingahle stop adapted to be disposed across the path in which the latch is slidable when the latter is interlocked with the epe a 3. The combination with a keeper. of a latch pivotally and slid'ably mounted thereon, cooperatingineans on the keeper and latch adapted to interlock when the latch is at oiie limit of its sliding movement, a. finger pivoted to the keeper at a recess therein and adapted to be disposed across the path in which the latch is slidable.

4; In combination, a keeper having an opening extending therethrough a pin bridging the opening, a latch pivotally and slidand adapted to be disposed adjacent said extension when the latch is held in non-turn- 111g position.

5. In COmlOIDEItIOII, a keeper having a reentrant portion, a latch pivoted to the keeper and disposahle in front of the said portion, a pin on which the latch is slidahle and on which it pivots, a lateral shoulder on the latch, an abutment on the-keeper, said shoulder aiid abutment adapted to prevent turning of thelateh when the latch is at one end of its slidalole limit, and a finger pivoted on the keeper and adapted to be disposed across the slidaole path of the latch.

6. Iii combination, a keeper, a latch pivote'd intermediate'its ends to the keeper said keeper having a cut-out portion within which one end of thelatch may swing, and a finger disposable adjacent that end of the latch within the cut-out said cut-out being of a length to allow sliding movement of the latch on its pivot, and intereng'aging means between the latch and keeper for holding the latch against turning movement when the latch is at one limit of its slidable limit.

In testimony whereof I aflix my signature.
